Biden was the big winner on Super Tuesday, sweeping the South but also picking up some surprising states en route to a victory that frames him as the party's frontrunner alongside Sanders. Bloomberg suspended his campaign and endorsed Biden the following day.

South Carolina Primary Results

Biden won South Carolina convincingly to revive his campaign and build momentum ahead of 25 primaries in March, beginning with Super Tuesday. Fellow Democratic candidates Steyer, Klobuchar and Buttigieg all dropped out in the following days, with the latter two endorsing Biden.

Nevada Primary Results - Caucus

Sanders was the winner in Nevada, dominating the Democratic field and prompting many voices in the media and beyond to label him the party's 2020 favorite.

New Hampshire Primary Results

In a closer-than-expected result, Sanders squeezed out a victory in New Hampshire, with Buttigieg and Klobuchar following. For many, the biggest takeaway was the losses for Biden and Warren.

Iowa Primary Results - Caucus

Buttigieg apparently won a tight race against Sanders in Iowa, but not before widespread technological difficulties prevented results from being recorded and released properly.
